TUBE OR ROLL FORMING MACHINE.

SPECIFICATION forming part of Letters Patent No. 749,114, dated January5, 1904.

Application filed January 16, 1903. Serial No. 139.307. (No model-l Toall whmn it may concern:

Beit known thatwe,CHARLES SURMANN and ROBERT D. DOUGLAS, citizens of theUnited States, and residents of Fall River, in the county of Bristol andState of Massachusetts, have invented new and useful Improvements inTube and Roll Forming Machines, of which the followingisafull,clear,.andexact description.

This invention has relation to certain novel and useful improvements ina machine for forming tubes, rolls, or the like, and has particularapplication to a mechanism of this character adapted to wind tubes,cloth, or the like.

Primarily we have in view as an object the production of atubing-machine the sections whereof forming the mandrel will be capableof being readily moved toward or from each other, thus enabling the tubeor roll to-a't'alt times have a positive hearing or support inside thesame, yet when it is desired to remove the tube or roll from the'mandrelthe cirjunction. with the sections, to form a rela-.

tively enlarged mandrel having a smooth circumferential surface.

We also contemplate providing an improved construction for moving themandrelexpanding means into and out of position between the free edgesof the sections, whereby we are enabled to avoid the use of cumbersomeand complicated toggle-joints, sliding rods, and the like.

A further object of the invention is to provide means for drawing thefree edges of thesections into contact, thereby reducing thecircumference of the mandrel when the expanding means have been movedfrom between the edges.

With these and other objects of a similar nature in view our inventionconsists in the construction, combination, and arrangement of parts, asdescribed in this specification,

delineated in the accompanying drawings,

Figure 1 is a central longitudinal sectional view of our improvedmandrel having a tube thereon, the frame and other interior portionsbeing shown in full lines. Fig. 2 is a transverse vertical sectionalview of a mechanism embodying our improvements, the sections of themandrel being shown in their enlarged or expanded position. Fig. 3 is asimilar view, but showing the mandrel in its contracted position. Fig. 4is a view of one of the supports or standards forming a part ofthe'interior frame of the mandrel. Fig. 5 is a detail perspective viewshowing the key employed in operating the mandrel-expanding means, andFig. 6 is a detail perspective view of a fragment of the key-bar.

In the accompanying drawings, wherein there is delineated a mechanismembodying our improvements, 1 designates a shaft or axle which isrotatably mounted in any preferred manner and which may be driven oractuated by any suitablyapplied power. Upon this shaft we have mountedstandards or supports which form what for the sake of convenience weterm the main frame. As will be seen especially'by reference to Figs. 1and 4, these supports comprise collar-like portions 2 2, each having anenlarged member or standard 3 formed at one end thereof, a boreextending entirely through the collars, and the enlarged member for thepassage of the shaft 1. The members of the frame may be secured rigidlyto the shaft in any approved manner, such as by bolts or pins, whichpass through the collar portions 2 2 and through the shaft, such pinsbeing shown in dotted lines in Fig. 1. Each of the members or portions 33 is provided with an extension or ear 4, which is apertured or bored,as at 5, (see Fig. 4,) to permit the passage of the rod 6, theconstruction being such that the apertured portions of these supports orstandards form bearings for said rod. The rod 6 is provided with acollar or washer 7 near each end,

which collars bear against the outer surfaces of the extension 4:, andbearing against these washers or collars 7 7 are apertured lugs 8,

formed on the interior edge surfaces of the approximatelysemicylindrical mandrel-sections 9. As will be observed particularly byreference to Fig. 2, the under surfaces of the free longitudinal edgesof the sections are beveled or inclined, as at 10, for a purpose to behereinafter described, the immediate contiguous portions of the sectionsbeing approximately fiat or parallel to each other, as at 11. It is tobe noted that when the sections are closed so that the edges 11 are in aposition to contact the mandrel has its smallest possible diameter incross section. For the purpose of expanding the mandrel we have providedthe following means: Formed in the end of each of the supports 3 3,opposite the ear 4, is an orifice 12, each orifice beving adapted topermit the passage therethrough of an end portion of a bar 13,approximately similar in construction and proportions to the rod 6. Eachend of said bar is formed with a flattened or squared portion 14 toprovide a grasping or gripping surface for a wrench, and mounted neareach of the flattened portions is a cam -key comprising a collar portion15, adapted to be secured through the medium of a suitable screw 16 tothe bar 13, and formed integral with this collar portion is an extensionor cam 17. Each of the supports 3 3 is provided with a socket orradially-extending bore 18, as is shown by dotted lines in Fig. l, andwithin each socket is adapted to be seated a stud 19, the stud beingconnected with and supporting a key-bar 20. This key-bar forms animportant feature of the invention and hasits uppersu rface slightlyconvexed, as at 2l,and inclined downwardly and outwardly away from thecurved surface are the sides or shoulders 22, a short vertical abuttingwall 23 being formed between the convexed top and the upper edge of theshoulder, such wall being adapted when the bar is in itsmandrel-expanding position to bear against the vertical edges 11 of thesections of the mandrel 9. Secured a short distance from each end of thebar and extending downwardly from the under surface thereof is a plate24, provided with a slotted or recessed portion 25, adapted to form alip or extension 26, the recess being in alinement with the curvedextension or cam portion 17 of the key, the construction being such thatwhen the shaft or bar 13 is turned for the purpose of moving the barradially outward the cams 17 of the keys 15 will strike against theupper walls 27 of the plates 24 and move the bar; but when it is desiredto draw the bar radially inward the key is turned in the oppositedirection and the cam portion abutting against the lower shoulder or lip26 forces the key inward. For the purpose of drawing the semicylindricalsections intoa position of contact any suitable means may be employed,such as the tension-springs 28, connected at one end to the shaft 1through the medium of books 29, and at the outer ends these springs aresecured to the semicylindrical sections of the mandrel 9 by similarbooks 30. It is of course to be understood that any suitable number ofthese springs may be employed and any suitable number of keys andplates, this depending upon the size of the machine. The outwardmovement of the cam-key away from the locking-bar is limited by stops orstuds 31, formed on the frame-standards 3.

From the above description, taken in connection with the drawings, theconstruction and operation of the machine will be readily apparent. Thekey being forced radially outward spreads the sections or jaws of themandrel into the position shown in Fig. 2 and the strip of paper or thematerial A to be rolled is wound around the mandrel to'the desiredthickness. When it is desired to remove the tube from the mandrel, awrench or other suitable means is applied to the fiattened or squaredend of the rod 13 and such rod is turned to bring the cam portion of thekey into contact with the lower shoulder and the key-bar is turnedradially inward toward the main shaft. The tension-springs as soon asthe key-bar leaves the space between the semicylindricalmandrel-sections draw the latter together into abutment or contact attheir longitudinal edges, and the circumference of the mandrel beingthereby greatly reduced the tube or roll may he slipped from the same.

Many advantages incident to a device of this character will beimmediately apparent. Itis to be noted that We avoid the use oftogglerods, levers, and the like for holding the mandrel in its expandedor reduced position and at the same time have provided a structure whichis economic, extremely durable, and capable of acting with greatpositiveuess. Heretofore in devices of this general character onedisadvantage has been incident to the same-namely, that when an attemptwas made to remove a tube or roll from the mandrel only a small sectionof the semicylindrical wail could be moved inward, the main portion ofthe circumference being fixed or rigid, and it was necessary to strikethe tube a sharp blow upon the body or circumference thereof to loosenthe same upon the mandrel, which striking or tapping oftentimes resultedin the abrasion or damaging of the material and the flattening ordistortion of the tube. In the present instance the diameter of themandrel-body is so reduced that the tube maybe removed with facility andwithout any such striking or tapping as has been mentioned. It is to beobserved that in addition to forming paper tubes or the like upon ourmandrel it is also exceedingly convenient for the purpose of windingcloth or any material, in fact, this being accomplished by placing apaper tube upon the mandrel and expanding the latter, so'that itfrictionally holds the tube, and then winding the cloth or otherproducts upon the said tube. When the desired quantity of goods has beenrolled or wound upon the tubes, the size of the mandrel is reduced, asheretofore explained, and the tube with the goods thereon is removed.

While we have shown and herein described one particular embodiment ofour invention, we wish it to be understood that we do not limitourselves to the precise details of The illustration herein, as theremay be modifications and variations in some respects without departingfrom the spirit of the invention or sacrificing any of the advantagesthereof.
